Bluetooth - Failure to automatically bring up the hci0 at startup

I've got a Bluetooth dongle:

Bus 003 Device 003: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

Which I need for a BT keyboard. I've already followed the instructions from https://wiki.archlinux.org/index.php/bluetooth_keyboard , and it seems to work, but after a (re)boot need to manually enter "hciconfig hci0 up" to get it working... At startup, the interface is DOWN, after I bring it up manually the keyboard seems to work well...
